My invention relates to bags or envelopes, sometimes called handle bags,in which suitable carrying and locking means are incorporated in andform part of the bag.

Some of the objects of my invention are:-

1. To incorporate, in a paper bag, carrying means and locking means theoperations and functions of which are, respectively, independent.

2. To provide in a bag of that kind a handle to which freely protrudesfrom the bag.

3. To provide in a paper bag a handle which permanently protrudestherefrom.

4. To provide closing means on the sides of the open end of a paper bag,so that the contents it of such a bag may be centrally disposed thereinand be retained in such a position.

5. To provide independent closing means on paper bag which areseparately folded over and locked to the bag simultaneously with thefold- Zll ing operation.

6. To facilitate the closing of a paper bag by folding only parts of theupper bag end in the locking operation.

I attain these and other objects by the devices as illustrated in theaccompanying drawing, in

' which:

Fig. .1 shows the developed blank of the bag of my invention.

Fig. 2 shows a top view of such a bag in a to closed position.

Fig. 3 shows the corresponding side elevation of my bag.

Figs. 4 and 5 show two modifications of the open upper ends of the bagof my invention. 33 Similar numerals refer to similar parts throughoutthe various views.

The bag blank of Fig. 1 comprises a back wall 11, a front wall 12 andextensions 13 and 14, and

l me

15 and 16, respectively, on the sides of said walls.

In making up the bag the extensions are folded onto the wallsalong thescored lines 17 and 13, the two walls of the bag are folded upon eachother along the scored line 19 and then the extensions 13 and 15, and 1dand ldare glued together, respectively, so that they extend into theinterior of thebag as shown in Fig. 3. Since the extensions 13, 15, and1d, 16 would interfere with the goods placed into the bag and would tilt13 and 14, or the extensions 15 and 16 are gummed 5&5 on the side whicheventually comes to face the sec, Serial No. 466,337

(on. see-es) I adjoining wall, before they are folded over along thescored lines 17 and 18.

Reinforcing pieces 20 and 21 are glued onto the insides of the wallsnear the ends of the blank. The reinforcement 20 covers part of the backwall 11, as well as the handle extension 22 and part of the lockingflaps 23 and.24. The locking flaps 23 and 24 connect to the back wall 11along scored lines 25 and 26 and are severed from the handle extension22 by cuts 27 and 28, respectively. The openings 29' and 30 are punchedthrough the reinforced parts of the front and back walls in such amanner that the respective openings 29 and 30 register with each other,when the walls are folded onto each other along the scored line 19.

Upon the locking flaps 23 and 24 scored lines 31 and 32 may be provided,from which extend the trapezoidally shaped wings 33 and 34,respectively. These wings 33 and 34 are provided in the locking flaps bymeans of the substantially trapezoidally disposed cuts 35 and 36. Alongthe scored lines 31 and 32 the wings 33 and 34 are shorter than thevertical sides of the openings 29 and 30, whereas the opposite sides ofthe wings 33 and Marc longer than said vertical sides of the openings 29and 30.

The scored lines 31 and 32 are indicated in Fig. l, in order moreclearly to illustrate how the respective wings may be pushed out fromthe respective locking flaps by the action of a finger. Lines 31 and 32however do not have to be scored in the practical application of myinvention.

A cut 37 is provided in the handle 22, which surrounds the elongatedpiece 38. Said piece 33 may be folded back onto the handle extension asshown in Fig. 3 thus providing a round edge 39 around the opening 40.The opening ill is of sumcient width to accommodate several fingers ofthe user alongside of each other, and the folded round edge 39 preventsthe paper from cutting the hand of the user while he or she is carryingthe bag. I

Fig. 3 shows, in closed. position, the bag which is formed out of theblank of Fig. 1. To close the bag, the user successively bends thelocking flaps 23 and 24 over the front 12 of the bag and simultaneouslypushes the respective wings 33 and 3% through the openings 29 and 30 ofthe bag. Since .the free ends of the flaps 33 and 3d are wider than theopenings 29 and 30, the wings remain extended through the-upper ends ofthe bag and securely retain the bag in a closed position.

Fig. a shows, in an open position, a modified bag of my construction. Itdiffers from the bag Oil lid

of Figs. 1, 2 and 3 by a reversal of the arrangement of the openings 29and 30, and of the wings 33 and 34. The openings 29 and are provided inthe locking flaps 23 and 24, and the wings are provided in the walls ofthe bag by corresponding trapezoidal cuts; In closing the bag of thismodification, the user folds the flaps 23 and 24 onto the front wall andthen pushes the wings 33 and 34 through the openings 29 and 30 in thelocking flaps. By means of this modification I provide a very stronglocking means, because the wings 33 and 34 are not only cut out of thereinforced material of the bag, but two wings, in a double layer, as cutout of the front as well as the back wall, are used on each side of thebag.

In the modification of Fig. 5, the locking means are similar to thelocking means of the bag shown in Figs. 1, 2 and 3. In fact,disregarding the handle extension, this view shows how the bag of Figs.1, 2 and 3 looks when it is not closed.

But in the view of Fig. 5 I show a handle extension 41 on the front wall12 as well as on the back wall 11. The two handle extensions areperforated in registry with each other in an opening 42, which serves toaccommodate the hand of the user. The corresponding blank, as comparedwith I the blank shown in Fig. 1, would also show a handie extensioncentrally extending from the lower end of the blank, and it would bereinforced by the correspondingly extended reinforcing piece 21. Byarranging my bag in this fashion I obtain a much stronger handle, andthe convenience of the handle for the user may be enhanced by bendingover, upwardly, the portion of the paper originally contained in theopening 42, thus providing a folded edge in a manner similar to thefolded edge 39 of Figs. 3 and 4.

It is clear, that the openings 29 and 30 and the cuts 27, 28, 35, 36 and37 are provided in the bag, after it has been assembled,by a singlestamping operation. This stamping operation comprises the making of theopening 42 in the manufacture of the modified bag shown in Fig. 5.

Although I have shown and described one form of embodiment of myinvention in detail, yet I do not wish to be limited thereby, except asthe state of the art and the appended claims may require, for it isobvious that various modifications and changes may be made in the formof embodiment of my invention, without departing from the spirit andscope thereof. a
